OBJECTIVE To determine the molecular epidemiology of extended-spectrum β-lactamases (ESBLs) and plasmid-mediated quinolone resistance (PMQR) in Escherichia coli isolated from farmed fish in China. METHODS E. coli was isolated from fish gut samples from fish farmed throughout Guangdong province and tested for the presence of the β-lactamase genes and PMQR-encoding genes using PCR and DNA sequence analysis. Co-transfer of plasmids encoding for ESBLs as well as PMQR determinants was explored by…

High Prevalence of β-lactamase and Plasmid-Mediated Quinolone Resistance Genes in Extended-Spectrum Cephalosporin-Resistant Escherichia coli from Dogs in Shaanxi, China
TLDR
High prevalence of β-lantamases and PMQR genes were detected among ESC-R E. coli from companion animals, and virulence genes fimH, iutA, fyuA, malX, iha, and sat were more prevalent in phylogenetic group B2.
SCREENING FOR EXTENDED-SPECTRUM BETA-LACTAMASES PRODUCING ESCHERICHIA COLI ISOLATES IN FISH SAMPLE AND PROFILING FOR ANTIBIOTICS SUSCEPTIBILITY
TLDR
This study aims to detect extended-spectrum beta-lactamases (ESBL) production by enterobacteria isolated from locally harbored and imported fresh and dry fishes.
Co-prevalance of PMQR and 16S rRNA methylase genes in clinical Escherichia coli isolates with high diversity of CTX-M from diseased farmed pigeons.
High Prevalence of Extended-Spectrum β-Lactamase-Producing Enterobacteriaceae in Wild Fish from the Mediterranean Sea in Algeria.
TLDR
The results highlight for the first time the diffusion of multidrug-resistant Enterobacteriaceae isolates carrying resistance and virulence genes in fish from the Mediterranean Sea in Algeria.

Isolation and molecular characterization of extended-spectrum β-lactamase producing Escherichia coli from industrial food animals in Mekong Delta, Vietnam
TLDR
Results suggest that chickens and pigs in Mekong Delta, Vietnam used for food industry could also serve as reservoirs of ESBL-EC isolates carrying virulence genes.
High frequency of virulence genes among Escherichia coli with the blaCTX-M genotype from diarrheic piglets in China.
Incidence and antimicrobial susceptibility pattern of extended-spectrum-β-lactamase-producing Escherichia coli isolated from retail imported mackerel fish
TLDR
The study result indicates that the mackerel fish might be the possible reservoir of bla CTX-M gene and may contribute to the dissemination and transfer of these β-lactamase genes to humans through food chain.
Multiple transmissible genes encoding fluoroquinolone and third-generation cephalosporin resistance co-located in non-typhoidal Salmonella isolated from food-producing animals in China.
Antibiotic Resistance Profiles and Molecular Characteristics of Extended-Spectrum Beta-Lactamase (ESBL)-Producing Escherichia coli and Klebsiella pneumoniae Isolated From Shrimp Aquaculture Farms in Kerala, India
TLDR
Evidence is provided that shrimp aquaculture environments can act as reservoirs of multi-drug resistant E. coli and K. pneumoniae and a low prevalence of ESBL-producers was found in the farms, most likely due to the reduced antibiotic usage in the shrimp farming sector.

High Prevalence of Plasmid-Mediated Quinolone Resistance Determinants qnr, aac(6′)-Ib-cr, and qepA among Ceftiofur-Resistant Enterobacteriaceae Isolates from Companion and Food-Producing Animals
TLDR
Three kinds of plasmid-mediated quinolone resistance (PMQR) determinants have been discovered and have been shown to be widely distributed among clinical isolates: qnr genes, aac(6′)-Ib-cr, and qepA, and their genotypes were determined.
Prevalence of β-lactamases and 16S rRNA methylase genes amongst clinical Klebsiella pneumoniae isolates carrying plasmid-mediated quinolone resistance determinants.
Prevalence of plasmid-mediated quinolone resistance qnr genes in poultry and swine clinical isolates of Escherichia coli.
Detection of Plasmid-Mediated AmpC β-Lactamase Genes in Clinical Isolates by Using Multiplex PCR
TLDR
A multiplex PCR technique was developed for identifying family-specific ampC genes responsible for AmpC β-lactamase expression in organisms with or without a chromosomal AmpCβ-l lactamase gene.
Increased prevalence of plasmid-mediated quinolone resistance determinants in chicken Escherichia coli isolates from 2001 to 2007.
TLDR
It was showed that PMQR determinants were highly prevalent in chicken E. coli isolates in China with a trend of increase from 2001 to 2007, and could potentially fuel the rapid development of fluoroquinolones resistance.
Prevalence of rectal carriage of extended-spectrum beta-lactamase-producing Escherichia coli among elderly people in community settings in China.
TLDR
The results show the importance of the intestinal tract as a reservoir for ESBL-producing isolates in community settings in China and that the use of antibiotics in the past 3 months is clearly linked to rectal carriage of ESBL producers.
Regional survey of CTX-M-type extended-spectrum β-lactamases among Enterobacteriaceae reveals marked heterogeneity in the distribution of the ST131 clone.
TLDR
The CTX-M-15-producing RE1 clone (strain A) is the predominant clone in the West Midlands and has spread throughout the region since its emergence in an outbreak 3 years earlier, showing the rapid spread and diversification of CTX/M-producing Enterobacteriaceae over a 3 year period.
Molecular analysis of antimicrobial resistance in gram-negative bacteria isolated from fish farms in Egypt.
TLDR
The first report for molecular characterization of antimicrobial resistance in Gram-negative bacteria isolated from fish farms in Africa is conducted, and results showed that 72 isolates contain tetracycline resistance genes and 19 isolates were positive for class 1 integrons with 12 different gene cassettes.
Prevalence of plasmid-mediated quinolone resistance in Escherichia coli isolates in Wenzhou, Southern China, 2002-2008.
TLDR
PMQR genes are present in both quinolone-resistant and -susceptible isolates and can also be transferred by conjugation experiments, thus suggesting a likely future increase in qu inolone resistance.
Characterization of clinical Escherichia coli isolates from China containing transferable quinolone resistance determinants.
TLDR
The great genetic variation of E. coli hosts containing transferable quinolone resistance determinants demonstrated the high transmission capacity of these mechanisms, and it is urgent to characterize and block their transmission routes in order to preserve the utility of quinols.
